Dear silver18,
I updated from 1.9 version to 2.1 Komic with written method on first page.
It works fine for example cover view mode or some old normal Komic specification.
But i have 2 problems on new 2.1 version.

1)I guess that i know this answer but i'm curious at for new version.
I copy my Cbr files on Gallery folder and i used Decompress button on Komic.
But i get empty files and broken files error on Komic.
I tried twice this work, but i can't open my Cbr files.
(Files name are started 1,2,3 etc and IMG1, IMG2 ..etc)
Should i unrar this cbr files with winrar and Should i rename files with any image app? Because this is same old file name problem.
But I hope maybe you know different solution for new version.

2) I can't use contrast and brightness menu.
I press the button, but does not change.
I can not display the contrast and brightness menu screen.
